Answer:
its just 9
Step-by-step explanation:
Divide: 3 : 1 / 3 = 3 / 1 · 3 / 1 = 3 · 3 / 1 · 1 = 9 / 1 = 9 Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator,
B=22.62
16/sin30=b/sin45
16sin45/sin30 =22.62
